ABSTRACT:
A waveguide having a pair of quarter-wavelength impedance transformers and adapted to divide and combine microwaves. The pair of quarter-wavelength impedance transformers includes two strip transmission lines connected together at one end, two ground conductors each located adjacent to and spaced from a respective one of said strip transmission lines, each said ground conductor serving as a ground potential at least mutually to the adjacent strip transmission line, and a dielectric substrate supporting thereon said strip transmission lines and said ground conductors. The two strip transmission lines may be connected to each other at numerous positions by resistors.
